ABSTRACT:
Apparatus for converting weak light, or light of low intensity, to electrical signals descriptive of such light. The apparatus is capable of sensing differences in photon flux over an area of detection, that is, sensing a pattern of lighter and darker areas. An important application of the apparatus is in spectroscopy and spectroscopic anaylsis, where it is desired to record a spectrum in other than visual form.
